Maybe you haven’t heard. It’s no longer just about the lubricant, its performance, quality or price.
The days of awarding a supply contract to the lowest bidder which happens to be a national brand is not a forgone conclusion. Much more is at stake and many factors impinge on this important decision. Indeed things have changed in the world of lubrication - one could say the field is starting to reinvent itself.
Today’s lubricant customer is more sophisticated and demanding. The watchwords are “world-class” and “core competency”. It has been said that if you want world-class reliability you need world-class lubrication. To be world-class at lubrication means you must have world-class . . .
Though typically treated as a commodity by many, the lubricant is a vital component of the machine. For many organizations, the quality of lubrication is the single greatest factor that influences machinery reliability and productivity. Sure, without any lubrication, the machine won’t run. But the quality of lubrication also affects machine reliability and efficient operation in less obvious ways.
Many of today’s lubricant suppliers offer an a la carte program of goods and services. Some offer full service, while others serve niche-specific markets, each with varying value propositions. There are many differentiating factors among lubricant suppliers. For this reason, matching the product/services mix to real applications and business needs is the challenge at hand.
The user organization must decide whether it wants to strictly buy lubricants or if it wants to purchase lubrication with services bundled in. If your intention is to just buy lubricants, you could be paying extra for unwanted services like oil analysis and technical support. If your desire is to buy lubrication, be sure you’ve optimized the content of your value package . . . taking no more or no less than you want.
Often lubrication services go unclaimed due to a lack of execution by the supplier or lack of understanding by the customer. Sometimes the customer is simply unaware of the availability or importance of strategic program elements. With that said, perhaps it’s time to revisit the many questions and issues that surround the lubricant supply decision. Consider the following:
Does the machine application, including thermal, energy conserving, and service life issues, demand the use of specific base oils, for example: synthetic, hydrocracked or mineral (Group I, II)? How about biodegradability, toxicity and food-grade requirements? Is it compatible with machine finishes, coatings, seals, etc.?
Do the suppliers’ products come in a suitable range of viscosities for each grade?
Are additives compatible with machine metallurgy, elastomers, coatings, seals and operating environment?
Will the supplier assist with custom formulations where catalog products won’t serve application requirements?
Is the lubricant (base oil and additives) compatible with close-proximity contaminants such as caustics, nuclear radiation, ammonia, refrigerants, natural gas, H2S, etc.?
Do lubricants meet industry, government, OEM, requirements/regulations - including any outlined by NLGI, API, GM LS-2, ASTM, GE, US Steel, SAE, ISO, NRA, AGMA and IP?tion, ammonia, refrigerants, natural gas, H2S, etc.?
Do published product performance data meet or exceed machine requirements or client expectations? Does the published test data represent typical products or minimum performance standards? Has independent lab testing been used to validate performance data for the finished products, or has the data simply been passed down by the additive supplier?
Is the supplier or brand known for performance-formulated lubricants or price-formulated lubricants? How does this match the needs of the customer?
Can the lubricants be filtered to the required levels without loss or damage of critical additives?

Now, a word about price. Many people have heard of “life-cycle costing” when it comes to lubrication and related services. Simply stated, this important principle directs attention to the total cost of ownership as if the lubricant were a durable. The initial cost of a gallon of oil or pound of grease is not regarded as the main factor. Instead, other things that occur over time gain greater importance, such as how will the lubricants and program of services affect the following:
The next time you award a supply contract for lubrication, take the time to actually determine your company’s needs. Begin by polling the stakeholders in the organization and close technical advisors. Create a list of factors, such as these listed here, that are potentially important and have the buying team weigh these factors in relation to the goals of the organization. The process may reveal that you have only been buying lubricants, when what you really wanted was “lubrication”. Conversely, the process may reveal that you have been paying for services that you don’t value, or would prefer to buy elsewhere.
When was the last time your company reviewed its lubricant supply relationship? Is there room for improvement to move your lubrication program steps closer to world-class? The savings and benefits may prove very rewarding.
1. Assemble a representative group of stakeholders and technical advisors - your strategic buying team.
2. Explain and discuss the objectives and selection process.
3. Through the leadership of a knowledgeable and objective facilitator, brainstorm to identify what criteria are important to the organization.
4. Review the criteria and combine them into the smallest number of factors without compromising content. Refrain from comment about the value or importance of any criteria.
5. Using a modified Delphi technique, have each stakeholder secretly rate the condensed criteria list using a value scale. No discussion about the value or importance of the criteria should occur. The secret ballot helps to limit group bias.
6. Have the facilitator gather the rating information and present the mean, median and range for each criterion to the group. Again, no discussion about the results is allowed.
7. Team members are then given a chance to re-rate the criteria using secret ballots.
8. The results are again presented to the group. Usually, the distribution tightens at this point.
9. Open the floor for discussion about the criteria.
10. Accept the group’s decision. Proceed with the structured evaluation of lubricant suppliers with confidence. The process is carried out by interviewing candidate supplier representatives, studying their proposals in detail and talking to references. Score the information that is gained for each supplier using the system of weighted value factors.
